LOCK.

Be it known that I, Morris; citizen of Russia, residing "at'New York, in the county and State of'New' York, have inf vented certain newanduseful Improvements in Locks, of which the following lis a lfull, clear, and exact speciiication.

This invention relates to locks, and `has for its object te provide a jimmy-proof flock having a vplurality of bolts ofdiiferent types, thereby increasing the security of the fas'- tening.

The invention conteinplatesv they provision of swinging hook-shaped bolts lon the keeper oi a lock, said bolts being `actuate'dfby' a slid'- ing bolt in the lock casing when sa'id'sliding bolt is projected into the keeper. The hookshaped bolts are adapted to interlock with the casing` of the sliding. bolt, -thus forming a double' acting lock andkeeper inwhich the sliding andswinging' bolts lare combined.

The arrangement of the bolts is such that a Vburglar cannot saw through them jor jimmy the lock.

A 'further object of theinvention is to facilitate the operation ofthe hook-shaped 'bolts by the sliding bolt'by giying the latter al step by stepmovement in projecting and `retracting`the same. Another object isgto adapt the sliding bolt tofbe actuated bysepa'- rate rollbacks arranged lout of alinement von the line III- III of with each other and controlled by :different key locks arranged on opposite sides of the door. A further object is te increase the sc curity of the'lock vbyhavin'gQthe vcasing for the lsliding bolt overlap and interlock with the casing for the swinging'bolts.. Other objects will appear asthedescription .proceeds.

The'inventi'oi'i will be first hereinafter defscribed in connection with theaccOmpany-ing drawings which constitutepartof the speciiicatioinand then V`more specifically defined inthe claims fat the end cfthedescription.

In the drawings, 1f designates .a portion of `adoor and 2 The casing 3 for the sliding bolt 4 has an angularly extending iiange 5 secured to the edge of the door by screws. 6 which are consShut. Said casing?) a part ofthe j amb therefor.v

casing for the swinging bolts 9, also' has anV4 angularly extending ange secured -to the edge of the chamber by screwsll which; are also concealed when thedoor is shut. The keeper 8 may also the chamber by screws V12, but these screws are not necessary to fastensaid-keeper in place. It will be seen that the screws 6 and 11, which are passed through the flanges 5` be secured to the face of and l0, cannot be removed when tlie'door j lis locked, so that yit isiinpossible for a bur-l glarjte open the door when locked by bodily removing either the lock or keeper.

The swinging bolts 9 lare hookshaped,'a`s

shown, and. normally extend in opposite directions from their pivots 13. The inner pivoted ends of said swingingvbolts have vprojecting lugs 14Lwhich extend into the path of. the sliding bolt L tand vare adapted to be engaged by thelatteras it is projected y for swinging the bolts 9 out ofthe keeper fand into engagement with slots v15 in ,the LippenV and lower edges of. the casing V5. When released, `the swinging vbolts 9 are revL16 -connected toma pin 17 in said keeper and @to the bolts 9 at 18.

The siidingboit i has when( i9 gravide@ with a horizontal slot20 into whicha fixed lug 2l inthe casing. 3 projects forguiding lthe bolt in its reciprocations andlimiting its '-slot 23- in a tumblerv24 which is p ivoted to a fixed-pin 25 inthe casing 3 and yieldingly tracted into thekeeper or casing8 springs pressed upward by a leaf spring 26. The slot 23 in the tumbler has a pair oflugs 27 and 28 adapted to interlock with' the lug 22 on the shank of the sliding bolt to prevent the latter from being moved except when said tumbler is swung downwardly, as shown in Fig. 4, to move said lugs 27 and 28 out of the path of the lug 22. As shown inl Figs. 3 and 5, the tumbler 24 normally extends in substantially horizontal position with its upper edge practically flush with the upper edge of the shank 19. In said upper edge of the shank 19 there are formed four notches, two of which 29 extend only part way through said shank, while the other two notches 30 extend entirely through the shank.

The sliding bolt is adapted to be actuated by either one of two roll backs 31 and 32 which are controlled by different key-actuated cylinderk locks 33 and 34. The cylinder lock 33 is mounted on the front Vof the casing 3 to be actuated from the inside of the door, while the cylinder lock 34 is mounted in the body of the doorso as to be accessible from the outside thereof, said lock 34 being connected to the -roll back 32, which is swiveled'on the backplate 35 of the lock casing 3, by a connecting piece 36, best shown in Fig. 2. The roll backs-31 and 32 are arranged out of alinement with each other, the tooth 37 of the roll back 31 being adapted to engage in the notches 29 of the shank of the bolt 4, while the tooth 38 of the roll back 32 is adapted to engage in the notches 30 in said shank. As shown in Fig. 2, the tooth 38 is wider than the notches 29 so that it will not enter them but will only be operatively engaged with the notches 30.

To facilitate the operation of the swinging bolts 9 by the projection of the sliding bolt 4, it has been found advantageous to provide for a step by step movement of said sliding bolt rather than to fully project it in one movement. Y For this reason, two of the notches 29 are provided to be engaged by the tooth 37 of the roll back 31, and two of the notches 30 are also provided for engagement by the tooth 38 of the roll 'back so that it requires two revolutions of either of said roll backs to fully project or retract the bolt 4. It will be noted that as the tooth of either ofthe roll backs is inserted into the corresponding notches in the shank of thesliding bolt, said tooth will engage the upper edge of the tumbler 24 and depress the latter so as to permit the lug 22 on said shank to pass over first one and then the other of the lugs 27 and 28. Fig. 3 shows the unlocked position of the sliding and swinging bolts, the locked positionl of said bolts being indicated in vdotted lines. Fig. 4 shows the positions of the parts when the tooth 37 of the roll back 31 is engaged with the first one of the notches 29, in which position it has depressed the tumbler 24 so asto release the `bolt 4 and has partially y projected said bolt. Fig. 5 illustrates the positions of the parts at the end of one full revolution of the roll back 31. A further revolution of said roll back will cause its tooth 37 to engagethesecond notch 29 in the shank'of the bolt v4 in the same manner as it engages Vthe irst notch, Fig. 4, .thereby fully projecting said bolt to the position illustrated in dotted lines in Fig. 3. The actuationV of the bolt 4 by the roll vback 32, controlled from the other side of the door, is the same as just described in connection with the roll back 31 except that said roll back 32 engages the notches 3Q instead ofthe notches '29 in the shank of said bolt.

The slots ,15' in the upper and lower edges of the casing 3 are preferably guarded by projections 39 on the front 'of said casing. Projecting lugs 40 are preferablyA formed on the front of the keepr 8 toengage iny open* ings 41 'in an extension 42 of the front plate Yof the casing 3 when the door is shut, thereby further increasing the security of the fastening.
